WATE R-MOTO R.

SPEGIFIQATION forming part of Letters Patent No. 241,800, dated May 24, 1881. Application filed February 3, 1881. (No model.)

To all whom it may concern:

Be it known that I, GEO. B. GRANT, a citizen of the United States, residing at Linden, in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Water-Motors, of which the following is a specification.

My improvement relates to water motors or engines by which the force of a stream of water under pressure is caused to give motion to machinery; apd it relates to an improved means of governing such a motor, or regulating the supply of water according to the work it has to do.

The drawing shows the mechanism in full.

The motor M is any form of rotary engine, water-whee], or hydraulic engine, and With its construction or mode of operation this invention is not concerned. It is any device which admits or discharges water through a pipe, I, and causes it to give rotation to a drive shaft, (1.

On the drive-shaft d is an arm, a, which carries a pawl, 11, acting on a ratchet-wheel, v, fixed to a driven shaft, S, so that that shaft is driven by the shaft d, but may keep up its motion by its own momentum when the shaft dis stopped.

Any form of friction-clutch may take the place of the pawl and ratchet.

Upon the shaft S, or turning with it, is a governor, G, of any form, which operates, through a lever, L, or any equivalent device, to open and close the governor-valve V on the pipe I.

The operation of the motor is as follows: The force of the water gives rotation to the shaft 01, and through the ratchet-connection to the shaft S. \Vheu the speed of the shaft S reaches any assigned limit the governor G shuts the valve V and stops or retards the motor. The ratchet-connection p and vallow the shaft S to revolve freely until the work it is doing exhausts the power stored up in the fly-wheel F, and causes the decrease of speed through the governor to open the valve V and start the motor again.

I am aware that a pawl-and-ratchet connection has been used between a water-motor and the machinery it drives, and also that a governor has been applied to check the supply of water to a water-motor; but

What I claim as my invention, and desire to secure by Letters Patent, is the following In combination, the motor M. driving-shaft d, paw] and ratchet p and Q7, driven shaft S, governor G, and governor-valve V, substantially as described.
